ApplicationLoadBalancedFargateService : Add Support for IPv6 on LB's #29039
Description
Describe the feature
I would like to enable IPv6 support on the load balancers created by ApplicationLoadBalancedFargateService and ApplicationLoadBalancedEc2Service.
Ideally this could be used as a new property for these two classes.``
Use Case
With the introduction of AWS charging for public IPv4 addresses (source), I am looking to enable IPv6 addresses on my ECS ALBs.
Proposed Solution
In the elbv2.ApplicationLoadBalancer class, there is a property for ipv6:
new elbv2.ApplicationLoadBalancer(stack, 'ALB', {
vpc,
internetFacing: true,
ipAddressType: elbv2.IpAddressType.DUAL_STACK,
});
My proposal would be to add the property ipAddressType to ApplicationLoadBalancedFargateService and ApplicationLoadBalancedEc2Service with the corresponding actions to enable when necessary. The default would be elbv2.IpAddressType.IPV4 which would make this an opt-in service.
